to feel a little bit upset by this woman's attitude?

[sweetmoonbeam]

This is my first time posting in this section (though I do read) but I'd welcome some other views as I have felt a bit upset by this.

On Friday, I realised I had left my debit card at home and I wanted to buy a present for a friend's new baby as well as a sympathy card for a friend who has recently lost her father. We have been friends since we were little girls and I know her family quite well and was upset by this myself, so I have to admit my mind was elsewhere when I went into the bank. I completely didn't notice that the queue was on the other side so inadvertently 'pushed in' and went to a cashier who I thought was available. She pointed towards the queue on the other side and I immediately apologised and went to the back of the queue.

That was completely my fault of course, but when I got to the cashier she 'greeted' me with the remark, "Waiting your turn this time, are you?" I was a bit taken aback by this but ignored it. However, all the time she was not having to ask me direct questions, she was muttering about me pushing in 'to herself' but not in a muted tone at all - I was obviously meant to hear. Things like:

"That lady was lovely about it. I'D have been FUMING if it was me you'd done that too."
"Do you not have to wait your turn in Cambridge then?" (I opened the account in Cambridge as I lived there then.)
"What are you in such a rush for that you pushed in, keen to get home I imagine."

I really didn't deal with it well as I got quite upset and kept apologising but now I've reflected on it I am quite angry. I didn't do anything all that terrible and it was a simple (though perhaps silly!) mistake on my part.

I think after I apologised once she realised she could make me feel even worse. I'm toying with whether or not I should complain to the bank, but I am not sure. Was what I did really so very terrible? I literally held the queue up for ten seconds if that as I walked up, apologised and walked away again!

YANBU, it was of course reasonable for her to (politely) point out the queue and ask you to wait your turn, but her later comments were rude and unprofessional.

Op, I would write to the bank and mention the incident - that cashier was out of order.
Something similar happened to me once in the supermarket queue. I had a trolley (one of those high ones with about a dozen things in it) and I genuinely did not see the basket only sign right above the checkouts. I too had things on my mind and had had little sleep.
A customer next but one behind me told me it was a basket only till and I guess wanted me to remove my things from the conveyor belt and rejoin another queue. I apologised and said it was a genuine mistake and turned my back on him - he kept going on and on about it to anyone who would listen and then started getting rude "i need my glasses changing etc". I ignored him all the while which was just fuel for his fire.
I apologised to the customer behind me and also the cashier. On my way out I turned to him and said "have a nice day, little dick".
Some people like to have the last word and think they are right all the time.

I absolutely HATE this passive aggressive attitude to people who accidentally push in. The ones who say "excuse me..." or a sarky "you're welcome". I have told DH not to do the whole sarky comment thing - he gets annoyed when people push in front of us, say getting on the bus.

I always seem to get these comments from other people. I am on the autistic spectrum and have some problems with spacial awareness and often bump into/past people. Or say they wait for me to pass through a doorway, but I don't thank them as I didn't know they were waiting for me. I am NOT rude. I just Do Not See Them. Or I can't read their intentions so I don't know they are doing something for me.

It genuinely hurts me when I am on the receiving end of those comments. It makes me want to shout that some disabilities aren't obvious and that maybe they should consider NOT judging people on one silly mistake. But I don't. Because ironically I am too damn polite. So I just walk away frustrated or with tears in my eyes and yet another dent to my self esteem.

I know that's irrelevant as you don't mention any condition yourself, and it was just human error on your part. And of course some people (not you!) are just plain rude and would happily cut into queues etc. But I'm just adding my experiences as somebody who is in your situation all too often.

Aside from all that, as someone who works in customer service, yes you should complain.

I would definitely put a complaint in. Very poor customer service. Very rude and snidey.

Pom If I'm in a queue, and someone goes to the front but then graciously apologises and moves to the end of the queue, I promise you, I don't bat an eyelid. Most people wouldn't. I certainly wouldn't make comments at all.
